Carbide rotary file cutter The cross-sectional shape of the rotary file CNC blade should be selected according to the shape of the filed device, so that the two appearances are consistent. When filing the inner arc surface, you should choose a half-pipe wrench or a pipe wrench (small diameter product workpiece); when filing the bottom corner surface, you should choose a semicircular file; when filing the inner bevel surface, you can use a flat file or a square file. File etc. When using a flat file to file the inner bevel surface layer, pay attention to make the narrow surface (wrinkle cloth) of the pipe wrench without teeth close to one surface of the inner bevel angle to prevent the bevel surface layer from being damaged by knocking.

The cemented carbide tool rotary file is mainly composed of cementite (WC, TiC) μm grade powder of high toughness silicide metal material, and cobalt (Co), nickel (Ni), and molybdenum (Mo) are used as binders. , Powder metallurgical products calcined in annealing furnace or radon reduction furnace. Cementites, nitrogen compounds, borides, etc. of ⅣB, ⅤB, and VIB metal materials are commonly referred to as cemented carbide tools due to their particularly high strength and melting point.

The adoption of the cross-section of the tire drill rotating pipe wrench]

The cross-sectional shape of the CNC blade of the carbide cutter rotary file should be selected according to the shape of the filed device, so that the two shapes are consistent. When filing the inner arc surface, you should choose a half-pipe wrench or a pipe wrench (small diameter product workpiece); when filing the bottom corner surface, you should choose a semicircular file; when filing the inner bevel surface, you can use a flat file or a square file. File etc. When using a flat file to file the inner bevel surface layer, pay attention to make the narrow surface (wrinkle cloth) of the pipe wrench without teeth close to one surface of the inner bevel angle to prevent the bevel surface layer from being damaged by knocking.

[Selection of the size of the pipe clamp teeth]

The size of the teeth of the pipe clamp should be selected according to the capacity size, processing accuracy, and raw material characteristics of the produced and processed products. Coarse-tooth pipe wrenches are suitable for the production and processing of large-capacity, low-precision specifications, large dimensional tolerances, large surface roughness scales, and soft raw materials; correspondingly, fine-tooth pipe wrenches are selected. When applied, it should be selected according to the remaining amount of machining, the precision of the specifications and the size of the surface roughness specified by the product workpiece.

[Adoption of specifications, specifications and models of aluminum alloy pipe wrenches]

The specifications and models of the cemented carbide tool rotating pipe wrench should be adopted according to the specifications of the product being processed and the remaining amount of processing. When the production and processing specifications are large and the capacity is large, pipe wrenches of large specifications should be used, on the contrary, pipe wrenches of small specifications should be used.

[Adoption of the coarse tooth D of the pipe clamp tooth pattern]

The tooth pattern of the tungsten steel material grinding wheel pipe wrench should be adopted according to the characteristics of the raw material of the product to be filed. When filing soft material products such as aluminum, copper, alloy steel, etc., it is better to use a three-tooth (milling tooth) pipe wrench. The three-tooth pipe pliers have large ulnar side, small wedge angle, large chip pockets, cutting is not easy to block, and the drilling edge is sharp.
